International Rectifier’s (SEE) RAD HARD technology
HEXFETs demonstrate virtual immunity to SEE failure. Additionally , under identical pre- and post-radiation test conditions, International Rectifier’s RAD HARD
HEXFETs retain identical electrical specifications up
to 1 x 105 Rads (Si) total dose. No compensation in
gate drive circuitry is required. These devices are also
capable of surviving transient ionization pulses as high
as 1 x 10
12
Rads (Si)/Sec, and return to normal operation within a few microseconds. Since the SEE process utilizes International Rectifier’s patented HEXFET
technology, the user can expect the highest quality
and reliability in the industry.
RAD HARD HEXFET transistors also feature all of the
well-established advantages of MOSFET s, such as voltage control, very fast switching, ease of paralleling and
temperature stability of the electrical parameters.
They are well-suited for applications such as switching power supplies, motor controls, inverters, choppers, audio amplifiers and high-energy pulse circuits
in space and weapons environments.
